FSST · Four Square Step Test

3 min · Time in seconds · lower is better

1 Before you use it

What it is

Step over four canes laid in a cross, clockwise then anticlockwise, as fast as safely possible. Forward, sideways and backward stepping in one timed task.

When to reach for it

When you want multidirectional dynamic stepping rather than straight-line walking — chronic ankle instability, and older adults with knee OA where turning and side-stepping is the reported problem.

2 Giving it

Scoring

Time the fastest of two successful trials. A trial is void if they touch a cane or lose the sequence.

What it doesn’t measure

Isolate a limb, or capture reactive/unplanned demand.

3 Reading the score

Interpreting it

**A cut-point around 15 seconds is commonly cited for increased falls risk in older adults.

Is the change real?

MCID 3.6 seconds. MDC 4.6 seconds, from a broader balance-impaired sample. Compare the change against this patient's own baseline as well as the figure. SourceMeasured in degenerative spinal conditions.

Student trap. Setting the canes up differently each time. The layout is the test.
